B. HAMLTN, OF CHICAGO, ILLINOIS.

.To all whom it may concern:

Be it known that we, FRANK B. HAMLIN, BERT' O. SUITs, and AUoUsTUs BRUNER, citizens of the United States, said HAMLIN residing at Chicago,.. Illinois, and said SUITS and BRUNER' residing at Indianapolis, in the county of Marion andState of Indiana, have invented certain new and useful 1m provemcnts in Gas-Controlling Valves, of which the following is a specification.

The object of our invention is to auto- .matically regulate the flow of gas-into-the house-service-pipe after the gas has been 'measured by passing through the meter, to maintain a steady pressure regardless of the varying number of .lamps or other burners which may be in use and turned on or off I from time to time.

' The object is to simplify and cheapen the construction of such gas regulators and to make them less liable to get out of order.

We attain the above, and other objects which will hereinafter appear, by the mech anism illustrated in the accompanying drawing, in which' v Figure 1 is a vertical sectional view of. a gas-controlling valve using a diaphragm to support the gas-supply regulating valves, the view showin the interior arrangement of the device. F1g. 2 is aftransversesection of same on the line 22 of Fig. 1. p A Like characters of reference ind cate like partsthroughout the several views of the :drawing.

The outer casing Lin-preferably of castet-compartment 5,

- circumferentially of the axis of the body 4 at its upper portion to support a larger diaphragm 8 than would otherwise be possible to use. For convenience in manufacture, the expanded-portion of the diaphragmcompar-tmentj 1s cast separately and is here shown as screwed u on the upper threaded end of the cy drical body 4. I It' is also'formedin two horizon- I tally separable members 9 and 10, having.

flanged ed es between whichthe diaphragm 8, is assem led and held'by bolts 11 wh1ch also secure the members 9 and 10 together.

- The diaphragm 8 forms a gas-tight closure for the upper end of the: outer casing or Specification of Letters Ilatent:

regulated by a spring closed valve 12. The

which contacts the diaphragm 8 whereby the latter will raise and open the valve 12 when said diaphragm is raised by gas pressure below. The depression of the diaphragm is occasioned by weights 14 which may be varied to suit'the requirements and an opening for access to the interior of the member 10is provided in the latter and is here shown as closed by a threaded cover 15- which screws into the correspondingly screw-threaded opening in said member 10. Should the diaphragm 8 break or leak the weights 14 will depress it, thereby releasing the ressure on the stem andvalve 12, permittmg the valve to be closed by its spring. This kee s the gas. leaking past the diaphragmv rom escaping from the upper compartment of the diaphragm housing and is an important feature of our invention.

The inlet-compartment 5has' a horizontal "Patented Apr. 11,1916. Application filed November 27, 1914. Serial No. 87 15214; I I i body 4'. air-vent'into theinterior of the upper member 10 is provided and'is opening 16 and a vertical opening 17, each' 7 formed with a standard pipe-thread. The two openings are to enable horizontal or vertical connection, accordin to which may be the I .most convenient to rye-made, and the hole not used for such connection is closed by means of a pipe-plug. The walls of the inlet-compartment 5. extend horizontally;-

into the shell and have upper and lower as seat of larger diameter. Both of said valve-- seats taper upwardly and receive correspondingly upwardly tapering valves 20 and 21.

The valves 20 and 21 are preferably formed on an internal metal casting comprising a body portion connecting the two valves having a. plurallty of radial plates 22. The 'ver-' tical edges of the 1plates 22 have. a sliding bear ng through t e valveropening in the bush1ng19 agamst said bushing whereby the A boss 23 at the upperend has a screw-threaded opening wh1ch receives-a stem 24. The upper end of the stem 24 is screw-threaded and passes through the diaphragm 8 and supporting plates 25 for said diaphragm, -n

a given position is retained by a loc ut 26 and locking-sleeve 27. The'weights 14 rest upon the upper plate25 and have a central hole by which they are assembled around the -what we claim asnew and [wishto secure sleeve 27. The stem 24 and valves are as-- sembled from below through an opening in the bottom of the casing Whichis subse-' quently closed by a screw-plug 28, a suitable recess 29 bein formed in its inner portion to prevent inter erence by the accumulation of naphthalene. A partition-wall 30, forming' part of the shell casting, divides compart ments 5 and 6 and the small opening 31 in' its center afiords passage for the valve-stem,

24 and also for the gas.

The side of the Shell 4 adjacent to the: feeding compartment 6- and outwardly thereof is provided with a' boss 32 which is threaded to receive a service-pipe through which the gas is. fed to aplurality of stove,

lam or ot er burners T e operation of our device is as follows:

Gas is admitted into "inlet-compartment 5 passing thence into feeding-compartment 6 7,

through valveopenings for valves 20 and 21.

From com artment Git enters the service pipe from 0s 32. The increased pressure in compartment 6 when no gas is drawn from it increases and passing through theo ening 31 enters the compartment 7 and li the diaphragm 8, (or the float 34, as the case may be,) raising same and withit the connected valves 20 and 21, eventually seating them if the pressure is-great enough, which cuts 0E the supply of gas and sto s the action. As soon as the presaure is ished by-gas being drawn to supply burners from the compartment 6 the ipressure is reduced and the diaphragm (or oat) sinks by reason of 7 the weights thereby lowering the valves and opening the passagewayspast them in proportion to the gas drawn of to supply the burners. An automatic fluctuation of the 't aaoe .1

or stove burners in use will occur, and the supply andpressure of gas will thus be'reg- V ulalted.

Having thus-fully described our invention,

by Letters. Patent-of the United States, is

'. In a gas-controllingvalve, the combina tion of 'a body comprismg an outlet-chamber and an inlet-chamber having walls extending into the outlet-chamber, said walls having two vertically alined valve-openings discharging into thej outlet-chamber, a valvestem, adiaphragin-chamber at the upper end of the'body communicating with the interior of the latter, a gas-tight diaphragm partition separating said diaphragmrch'amber'into upper-and lower 'comzartments, said diaphragm being connecte said upper compartment having a relic opening, a valve controlling said relief opening, ,sald :valve having a stem restingupon by the raising of the diaphragm, a spring toclose the. valve, two other taper ng valves both mounted on -.said first stem, said valves being connected by integral radial plates lower valve.

In witness whereof, we h'ave hereunto set our hands-and seals at Indianapolis, Indiana, this 24th day of October, A. D. one thousand nine hundred and fourteen.
